Yeah like you said it's very individual.
What is "thought" on bodybuilding forums to be 8% or 7% BF% is scientifically a bit higher than that, think DEXA scan, it measures fat around your organs, in your organs and your brains.
For example, here is when I have VERY lean but MUCH TOO SKINNY (long story)http://image.noelshack.com/fichiers/...3510-clem3.jpg

I was tested at 12% my DXA.

Young self-caring Paleo-eater from France.
(So please forgive the strange way I tend to express myself in your beautiful language )

The University near me does hydrostatic weighing I am tempted to do it just out of curiosity but on the other hand I am 6foot 182lbs with a 32-34 inch waist so I figure regardless of what my BF is I am doing OK.

Eating primal is not a diet, it is a way of life.

Don't forget to play!

I'm just curious because he looks great for his age and I'm of similar years. I bought a BF tester that is suppose to be pretty good. Not looking for and exact, just wondering what it's going to take. Haven't seen my abs since I started drinking beer. Age in Canada is lower at 18 and I started drinking well before that, soooooooooooo it's been a lonnnnnnggggggg time! LOL

I can almost guarantee you will never look like Mark Sisson. He has been into high endurance sports, body building, whatever, his whole life. He is seeing his genetic potential, same as you want to see, but sadly we all don't have that genetic potential to look like Mark Sisson. I'd be willing to bet he's never had a time when he didn't have visible abs.

I think for guys like you and me, the best we can hope for is to get rid of visceral fat, get off all meds, and then hit a healthy weight and stay there.

I'd say the only way it would be possible for a formerly chunky middle-aged man to end up like Mark Sisson would be with relentless training and possibly testosterone/steroid/hgh doping. Without that, you'd have to find a doctor who would test you and get your testosterone, thyroid, and cortisol into the upper 90% of ref range and then live in a gym for a couple years.
